android 当试图启动或停止服务器时adb挂起

(This这个问题肯定与ADB is not starting (no error message)有关，但没有明确解释是什么修复了这个问题，而且一遍又一遍地重新安装也不能说服我。）
当我像往常一样

$ sudo adb kill-server && sudo  adb start-server

我得控制它。
建议的adb_trace álà另一个问题产生如下结果：

# export ADB_TRACE=all
# adb start-server
system/core/adb/adb.c::main():Handling commandline()
system/core/adb/adb_client.c::_adb_connect():_adb_connect: host:version
system/core/adb/transport.c::writex():writex: fd=3 len=4: 30303063 000c
system/core/adb/transport.c::writex():writex: fd=3 len=12: 686f73743a76657273696f6e host:version
system/core/adb/transport.c::readx():readx: fd=3 wanted=4 <---- freezes here

strace稍微有点冗长，我得到了这个：

# strace /home/leo/Downloads/android-sdk-linux/platform-tools/adb start-server
... many

futex(0xffab8474, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 1, NULL, f742a700) = -1 EAGAIN (Resource temporarily unavailable)

rt_sigaction(SIGRT_1, {0xf7752680, [], SA_RESTART|SA_SIGINFO}, NULL, 8) = 0
rt_sigprocmask(SIG_UNBLOCK, [RTMIN RT_1], NULL, 8) = 0
getrlimit(RLIMIT_STACK, {rlim_cur=-4286578688, rlim_max=-9223372032703125888}) = 0
uname({sys="Linux", node="donleo", ...}) = 0
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3
connect(3, {sa_family=AF_INET, sin_port=htons(5037), sin_addr=inet_addr("127.0.0.1")}, 16) = 0
write(3, "000c", 4)                     = 4
write(3, "host:version", 12)            = 12
read(3, <---- freezes here

那么，接下来呢？

- 尝试解决此问题时发现的另一个问题是，通过SDK管理器更新SDK失败。它告诉我，我的Android SDK Platform-tools为16.0.2，希望更新到17。单击"安装"将永远挂起而不执行任何操作。我假设这两个操作都将无限期地等待来自同一组件的应答。[更新：]**删除组件成功了。现在安装它显示了一个问题（与更新相反，更新在日志中没有显示任何"红色"行），说停止adb不起作用。杀死adb后，更新通过了，但adb仍然拒绝工作。
- 更新：**我想我安装的adb本身可能被破坏的怀疑可以排除了。我使用手动下载的SDK，刚刚从ubuntu仓库（4.2.2 + git20130218 - 3ubuntu1）尝试了adb，它挂在完全相同的位置。

找到了。以bug report上非常有教育意义的评论的风格：

嗯......文件描述符3？

grrrrr！为什么？为什么？为什么adb没有超时之类的东西？为什么traccar --一个也有Android客户端的软件--使用ADB的端口5037作为它的IntelliTrac组件？他们使用所有的端口5000到5040。

# /etc/init.d/traccar stop

谢谢你的解答。
